I believe you’re referring to this article which describes increased chances of tibfib fractures in bindings that release laterally from the heel (all tech bindings EXCEPT Shift, Tecton, Vipec).

If so, it really isn’t about consistency of release due to pins at the toe, but rather how levering forces work when the point of laterally applied forces is near the toepiece on bindings that don’t release at the toe. This would equally apply to non-pin alpine bindings that don’t release from the toe (if they existed).
In early binding days before they were designed to release when skiing, tibfib fractures had high occurence rates. The releaseable toe was specifically designed to prevent this common injury. I can’t remember the figures but it was something impressive like a 95% reduction in rates.
